Product Introduction
10-inch 4KW Marine Navigation Radar for Fishing Boats | 36nm Range SYRSB-1004 - Saiyang
For captains of fishing boats and yachts needing reliable collision avoidance in coastal waters:Saiyang SYRSB-1004 provides a 36-nautical-mile range with a 4° horizontal beamwidth – detecting small targets like buoys and small boats where consumer-grade radars fail, while its 24V DC operation (10.2-40V range) simplifies retrofit on vessels with unstable power supplies.
Key Problems Solved
Dense target discrimination: 4° horizontal beamwidth separates close targets (e.g., channel markers near harbor entrances)
All-weather reliability: X-band (9410MHz) minimizes sea clutter interference compared to S-band in rainy conditions
Data integration: Native NMEA0183 & IEC61162-2 inputs for GPS, AIS, heading, and log data – no protocol converters needed
See further in coastal fog: 4KW transmit power + 36nm range
Spot small targets: 0.08us short pulse width for 0.125-1nm ranges (details objects like crab pot floats)
Connect to any plotter: VGA split port + dual-format AIS/GPS inputs
Power flexibility: Works on 12V to 36V DC systems (2.6A draw at 24V)
